Question

which option is correct. please give me answer​

Answer 1

Answer:

corrct answer is frequency

Answer 2

Answer:

The photoelectric emission occurs only when the incident light has more than a certain minimum frequency.

Explanation:

According to Einstein's photoelectric equation  

$K_{max} =hv-hv_{0}$

Since $k_{max}$ is positive, the photoelectric emission occurs only if,

$hv>hv_{0}$ or $v>v_{0}$  

The photoelectric emission occurs only when the incident light has more than a certain minimum frequency. This minimum frequency is called threshold frequency.
